Ok in that case /sys/fs/cgroup should still be mounted read-write. After
you login, what does /proc/self/cgroup show, and what does the tree under
/sys/fs/cgroup/freezer/ look like?
OK. I've got this from a login via SSH immediately following a
reboot of plato.
socrates@plato:~$ find /proc/self/cgroup -ls

Oh I meant cat /proc/self/cgroup.
Ah, right.
socrates@plato:~$ cat /proc/self/cgroup
9:perf_event:/
8:blkio:/

6:freezer:/

Ok, so now you run the prep.sh, then /proc/self/cgroup shows:
socrates@plato:~$ cat /proc/self/cgroup
9:perf_event:/socrates
8:blkio:/socrates
7:net_cls:/socrates
6:freezer:/socrates
5:devices:/socrates
4:cpu,cpuacct:/socrates
3:cpuset:/socrates
2:name=systemd:/socrates
? (We'll hope that the name=systemd one isn't a problem). Can you
show the result of
ls -ld /sys/fs/cgroup/freezer/socrates
ls -l /sys/fs/cgroup/freezer/socrates
then finally do the 'lxc-start -n container -l trace -o xxx' and attach
xxx one more time. I've got a bad feeling this won't give *new* info,
but at least I know where we're at at this point. Actually, exactly
how did you create the container? Could you create a new one using the
same command, start it, and make sure it fails the same way? (that
shoudl give me all i need to reproduce)
Looks like the script isn't working right... It doesn't seem to affect
my /proc/self/cgroup. Logging out and back in again didn't seem to
affect it either. Nor did re-running the script.
